VANADIUM-GOLD ALLOY.

Specification of Letters Patent.

Patented Aug. 11., 1914.

lifo"l'ih'evmhiig;;,-" fl 'lgihelepplicstion filed October 11, 1911, Serial No. 654,005. Divided an this application filell Gciober 22, 1912., Serial No. 727,169.

, and resident of New York, in the county and j Slate of New York,'heve invented a new ei'icl usefulVanadium-Gold Alloy, of which she following is e specification,

application for patent; Sex. No. v eel 11 1911 as s new and useiiiicrlicle elloys of mnedmm alloys with -an i A old Aside elf the ordinary way of p10- clucing such alloys by melting the metallic coiis'ziliieiits there are other ways of obta1n- 5111;; a metallic rcgiilus of a, gold vanadium elloy.

llh 'my present application, being a division 05 my previous cpplicatior'i No. 654,005 filed Och 11, 1911, I describe a BflB LlIOCl of producing vanadium gold alloys from venmlium com oumls and gold prep by using a chemical reducing agent l1. veclescriberl and cleimeil ininy co-v example carbon anal While I do'not such meshed I consider the resulting and oxygen, vanadium and sulfur, or vanadium and chlorin are mixed with a gold preparation of either chemical or physical character both parts preferably in. finest subdivision, e chemical reducing agent for example carbon is added and the Whole subjected lo heat. The regulus obtained from the chemical constituents represents a gold vanadium alloy which is obtained by a chemical reduction, taking place before and at the time of the alloy formation. The alloys produced by my said process possess very favorable properties in regard to strength and wear, and the described process affords the preparation of gold vanadium alloys with or without the presenceof' other metals accordin to the number and chemical relation of t e mixed mgrechents.

Having now fully described my invens 7 tion I claim: As a new article an alloy of vanedlum with gold.
